Three major inkjet photo papers (2)

Where is it difficult? One is paper base, known as RC or PE coated photographic base paper, currently reliant on imports. Mainland Lekai is a joint venture with Kodak, and 600 million is used for this project. Lucky is ready to give up the film and go all the way in this direction. The second is the coating formula, which is currently only controlled by the hands of a few large manufacturers. There are also many domestic manufacturers in the test, but the performance is far worse, the reaction is insufficient in density and color saturation. Third, the level of coating, the uniformity is more difficult to grasp.

Many friends sell paper, and a considerable portion of them are gummed papers, which are not waterproof papers. This paper has about 40 production lines in China. It is coated with swelling type gelatin on PE original paper, and it can swell with water-based ink, absorb the ink, and then gradually dry and image. So it is very suitable for HP type heat foaming machine, because the heat foaming machine's ink is highly water-soluble, but it is difficult to absorb the EPSON type pressure motor ink, because this type of ink is quick-drying. The technical difficulty of this kind of paper is almost no, only the manufacturer is willing to refuse to use good materials only, so now it has achieved 15-20 yuan per square, but it can not be used for printing photos. The reasons are: First, because its coating is water-soluble, it is not waterproof by nature, is affected by the climate too much, and the stability of the paper is poor. Second, it is only suitable for the heat of the hot foam machine, high water soluble ink, and this type of ink is almost all dye ink, dye ink storage capacity is simply not suitable for saving photos. Third, in the absence of a film, its highly reactive coating will quickly oxidize and yellow, and the adhesion of the coating to the paper base will be too poor and can be easily separated by hand. Fourth, after the printing of glossy photo paper is no longer a highlight, no gloss. All these are far from the requirements of the photo industry. Some friends may say that they can use film to improve the above phenomenon. However, this is an expedient measure to stop the symptoms. If you want to apply a film to a 5-inch patch, how do you cover it? Every home user who uses inkjet to print a photo should buy another laminator? It is water-proof and moisture-proof after printing before printing, which can make people feel uncomfortable, and the most important thing is its preservation ability, so the paper can only be positioned in the short-term advertising field.

The RC coated micro-gloss photo paper perfectly solves all the above problems.
